TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 513,110, dated January 23, 1894.

Application filed September 21, 1892. SerialNo.4=46,501. (No model.)

To all whom it may concern:

Be it known that I, JASPER N. HOWARD, a citizen of the United States of America, residing at Wichita,in the county of Sedgwick and State of Kansas, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification, reference being had therein to the accompanying drawings and the letters and figures of reference thereon, forming a part of this specification, in which Figure 1, is a top plan view of the machine, having portions broken away to more clearly show the construction Fig. 2, a sectional elevation on line X, X, of Fig. 1; Fig. 3, a similar View on lines X, X, of Fig. 1; Fig. 4, a bottom plan of the paper holding carriage of the machine; Fig. 5, a sectional elevation on line X, X" of Fig. 1, and Figs. 6, 7, 8, 9, 10, 11 and 12 are detailed views of portions of the machine.

This invention relates to certain improvements in that class of type writing machines wherein a single index key is used, adapted to be turned on a pivoted center, and by connected mechanism, bring the type into operative position, and consists in the particular construction and arrangement of parts, which improvements are fully set forth in the following specification and pointed out in the claims.

Referring to the drawings, a frame A, which is preferably of cast metal, is made of such form as to support the operative parts of the machine, and in its construction is made with transverse guide ways G, G, at one end upon which the paper holding carriage C of the machine is arranged to slide. Said carriage consists of a frame; one part comprising the end pieces S, S, and the longitudinal connecting bars 0 and 2 and ratchet bar R, the bars 2 and R being arranged, resting and sliding on the ways G, G, of the frame; and the other part comprising the end pieces S, S, hinged at their rear portion on bar 0, and of the longitudinal connecting parts S" and y, which frame supports the paper holding and feeding rolls R and R, as shown.

A rock shaft L is journaled at each end in the end pieces S of the carriage frame, and bears at either end a side extending arm 21 each of said arms resting under a portion 25, of the roll holding frame, in such manner that, when the shaft is rocked said arms will be operated to raise said platforms, upward, and thereby cause the said roli holding frame to turn on its hinged bearings and elevate the rolls R, B; said shaft L being provided with a centrally depending arm 20 which is engaged and operated to thus operate the shaft and its'arms 21. A rock frame, comprising a horizontal bar m and trunnions m is journaled, by means of said trunnions, in corresponding hearings in the frame A in such manner as to be parallel with the movement of carriage O, and so the bar on will rest adjacent arm 20 of rock shaft L. Said frame is further provided with a depending arm M.connected with a bell crank lever 9, which is fulcrumed to a standard 10 which is secured to the upper side of frame A, through the agency of a connecting rod 24; the said bell crank having one arm arranged extending down through an opening in frame A for the purpose of effecting such connection, while the opposite arm of said lever terminates with a finger key, which is adapted to be pressed down to operate the lever, which movement causes the said rock frame to be operated, which in turn engages arm 20 of rock shaft L, at any position of carriage O, and causes said shaft to be rocked, its arms 21 to be raised, and the hinged frame of the carriage to be actuated to elevate the paper holding rolls. If desired, said adjustment of parts may be held by means of an extending arm 6 of a swiveled post 11 which is arranged adjacent the horizontal portion of lever 9, by turning said post to bring said arm 6 over the lever, as shown in Fig. 3, but when the lever 9 is-not held by said arm e, a coil spring t, arranged on one trunnion of the rock frame m. m, and given tension by connecting one end with the frame A and one end with the said rock frame, will return said rock frame, connecting rod, and lever, to their normal position.

H represents a type bar head, and is made circular in form, and is provided about its pe riphery with a series of notches as shown at too a in Figs. 10 and 11, and with an annular groove a also shown in said figures, with an annular flange H on its upper side, and with a toothed gear wheel 13 on its under side, as shown.

2 represent the type bars, each bar being made at its lower end to fit a notch a of head H, and each bar being further provided with ahole arranged to register with the base of the annular groove a, of head H, when the bars are arranged in their notches a, and when thus arranged the said bars are jointly fulcrumed in their respective notches by means of a wire a" (see Fig. 11), which is arranged in the annular groove a, and passed through the holes of the type bars; the wire ends being suitably secured to hold the same thus arranged. The said type bars are further provided, individually, with an extending foot piece cl, at their lower end, and with a capital letter and a small letter at respective points at their upper portion, as shown in Fig. 9, (which represents the two characters of type of letter Dd,) and with a connected coil spring 3,

which is connected with the annular flange H of head 11. The feet at of the type bars serve as a part to be engaged by a downwardly moving device to operate them, and the coil springs 3 serve as a means of yieldingly holding them erect when not being operated. The said type bar head is arranged in a horizontal position on the upper central portion of the frame Aso as to bring the type bars adjacent the paper holding roll R, where it is pivotally secured by a stud N.

A toothed segment D is arranged on frame A in mesh with wheelBof head H, and is pivotally secured, between a cross-plate F and the surface of frame A by means of a rod 6, which also serves as a connecting rod of a lever mechanism. Said segment is made with an extending arm which terminates with a fork 5 wherein the machine index lever 4 is fulcrumed, as shown. At the under side of frame A is a lever 17 fulcrumed to a depending part 22, and connected at one end with the index lever 4 through the agency of rod, 6, and at its opposite end with a lever 18 which leveris fulcrum ed to frame A, as shown, and bears an upright arm 1 which terminates at its upper end with an over-reaching part, extending toward the type bar head, and in such position as to be immediately over the foot 01' of the type bar 2 which is brought to rest at the printing point, and by such arrangement of levers, a down movement of the free end of index lever 4 will cause a corresponding down movement of arm 1 of lever 18, causing the over-reaching part of said arm 1 to engage the foot (1 of the adjacent type bar, and thus operate said type bar so its type end will move toward and strike the paper holding rollR; the index lever 4 being adapted to be moved horizontally, at its free end, above an index plate, which is semicircular in form and bears the several letters of the alphabet, figures and other characters common in type writers, and when moved, correspondingly operates the segment D which 111 turn operates gear B and correspondingly turns the head H, and the type bars are so arranged that when lever 4 is brought above a certain letter or character, of the index, the corresponding type bar will be brought so its foot d will be under the over-reaching part of arm 1 of lever 18, so that a down movement, at such position, of lever 4, will cause said type bar to be operated, as described, for the purpose of causing the lever 4 to be exactly in line with the letter or character of the index. When brought down, it is made, at its under side adjacent the finger piece, wedge shaped, and about the index is arranged a notched rack 7, which is secured to frame A, and provided with a V-shaped notch in line with each letter or character, and when the lever 4 engages said rack, its wedge shaped part registers in a V-shaped notch, thus centering, or lining the lever, (see Fig. 6,) which insures the correct position of the type bars 2, as they are brought about to be operated.

Fulcrumed to frame A, adjacent arm 1 of lever 18, and arranged to operate transversely to said lever 18, is a lever 16 carrying on the upright portion a spring pawlP arranged to engage the teeth of the ratchet bar R" of the paper holding carriage C, the spring thereof being shown at P; a horizontally extending arm 23 of said lever 16, is arranged under a side extending lug 19 of arm 1, and the upright portion of said lever is connected, through the agency of a wire 9 with a coil spring in barrel 15, which spring yieldingly holds said lever inclined in one direction, holds arm 23 thereof against lug 19 of arm 1 with sufficient tension to support said arm 1 and hold the lever 18 and the levers connected therewith in their normal position. Bysuch construction and arrangement of parts, last described, at each down movement of index lever 4 a type bar 2 is operated to cause its type to strike roll R of the carriage C, and simultaneous with such movement the lever 16 is thrown to shift the pawl P backward a distance sufficient to engage the next succeeding tooth of ratchet bar R" of carriage O, by reason of lug 19 of arm 1 carrying down, therewith, on the arm 23 of lever 16, and as the index lever 4 is released the spring in barrel 15 will, by reason of its tension, reverse said movement and thereby release the operated type bar, and through. the agency of pawl P move the carriageG along on its way, one space, at each such movement.

As a means of raising pawl P so as not to engage the ratchet bar R, at times when it is desired to independently shift carriage 0 along on its ways, said pawl is provided with a side extending wing P (see Fig. 7) and a lever '12 is provided, fulcrumed on frame A as shown at 13, the said lever having a finger key, as shown, which is supported by a spring armfas shown in Fig. 1, and the opposite end portion 14 of said lever is arranged resting under the wing P" of said pawl, so that a down movement of the finger key of said lever will raise lever end 14 and cause it to engage the pawl wing and correspondingly raise the pawl.

E represents a hood placed over the type head H and type bars thereof, and serves as a protector for said parts, and is made open at the side adjacent carriage O in order that the type bars may strike the platen, and is cut away so as not to obscure the place where the type bars engage roll R of the carriage.

I represent ink rolls, and in Fig. 12 they are represented arranged in a frame I. Two sets of such ink rolls and frames, are used, one set being arranged within hood E at each side of the side opening of the hood, being held, so the type of bars 2 will engage therewith, when head II is moved in either direction, and be inked ready to effect a print, when they are brought into proper position for operation. Such position of the inking rolls is shown in Figs. 1 and 2, and the hood E is made with an opening adjacent each outer roll of each set, so that they may be accessible to be supplied with ink at times required.

Secured to an extending portion of one journal of roll R, of the carriage O, is a hand wheel J having on its inner side a ratchet wheel J, and fixed to frame end S is a spring awl J arranged engaging said .ratchet wheel. Rotation of the roll It is accomplished by operating the hand wheel J, the pawl J preventing a wrong direction of movement, and the ratchet J serving as a gage, so that a like distance may be made at each movement.

The paper employed in writing is passed from the rear,between the rolls R,R as shown in Fig. 2, and when being placed, the longitudinal curved, plate z, of the carriage, serves as a means of directing the paper upward, and when beyond said plate it is placed under a series-of clamping fingers 1;, which are attached to a rock shaft to, which is journaled, at its ends in bearings of upright portions of frame ends S, S, and is provided at one end with a laterally extending arm. to held up into position by means of a spring, as shown at w in Fig. 8, which spring serves as a means, in thus holding arms to, to exert a light tension to yieldingly hold down the series of fingers 'v on the paper, and when placing or removing the paper said arm w may be pressed down, which will correspondingly raise arms '0.

It has heretofore been stated that the type bars 2 are each provided with two type or characters, and it has been describedin what manner the paper holding rolls are elevated at times. The purpose of thus elevating said rolls at times, is to bring the type engaging side of roll B into position so the type at the extreme end of the bars 2 will at such times effect a print, while the other type of the bar will be too low to effect a print. While in the normal position of the roll R the lower type will effect a print and the upper type will be too high to effect a print, and as the lower type are preferablyof lower case and if it is desired to print all capitals said 7 key is held downby arm a of post 11 as described.

In the arrangement of the index of letters and characters of the machine, one space is left blank, as shown in Fig. 1, and the type bar corresponding with such space is either blank or omitted, and when the index lever l is pressed down at that place no print will be made, but the spacing pawl will be actuated to shift the carriage O the same, as when a print is made, which movement serves as a spacer, between words, at end of sentences, &c.,when spacing is required.
